Standard Chartered Bank Zimbabwe Limited v Kedson Nkomo

Nkomo, a bank teller employed by Standard Chartered Bank Zimbabwe Limited, cashed a cheque for $15,000 on 24 June 1996 made payable to Bright Taruvinga. The crossing on the cheque had been cancelled and authenticated by two senior bank officials. Nkomo checked the customer's metal Identity Card and, satisfied it matched the person before him, cashed the cheque after obtaining his superior's approval (required for cheques over $10,000). The cheque was fraudulent, created by two other bank employees (later imprisoned) who debited it to an innocent customer's (Mrs M.L. Crow) account. Taruvinga was traced and confirmed he was at work at the time and that two of his identity cards had previously been stolen. A handwriting expert, Blackmore, examined a withdrawal form and opined that Nkomo had written the details on it. Nkomo was charged with serious misconduct, gross negligence causing loss of $15,000, and failure to follow procedures. He was found guilty and dismissed. After unsuccessful internal appeals, the Labour Relations Tribunal ordered reinstatement or damages. The bank appealed to the Supreme Court twice.

• Whether the Labour Relations Tribunal's decision to order reinstatement or damages was irrational or so outrageous in defiance of logic that no sensible person could have arrived at it
• Whether the bank proved that Nkomo acted negligently in cashing the cheque
• Whether Nkomo failed to follow the bank's procedures in cashing the cheque
• The evidential value and reliability of handwriting expert opinion evidence in the absence of corroboration
• Whether the bank discharged its burden of proving the misconduct charges against Nkomo

The appeal was dismissed with costs.

The binding legal principles established are: (1) An employer bears the burden of proving misconduct charges justifying dismissal, and where crucial evidence (such as the metal Identity Card in this case) is not produced without satisfactory explanation, the employer fails to discharge this burden; (2) Expert handwriting opinion evidence requires corroboration by other evidence before it can be relied upon to establish guilt in disciplinary proceedings; (3) A court will not interfere with a labour tribunal's findings of fact unless they are so outrageous in defiance of logic that no sensible person who had applied their mind to the question could have arrived at them; (4) Where an employee follows proper procedures (obtaining superior approval, checking identification) and there is a reasonable possibility their account is true, negligence cannot be established; (5) Misconduct charges must be based on accurate facts - an allegation that an employee cashed a crossed cheque fails where the crossing had been properly cancelled by authorized personnel.

The Court made important observations about the reliability of handwriting identification evidence, citing South African authority (Hoffmann and Zeffertt, The South African Law of Evidence, 4th ed) to note that: (1) expert opinion on handwriting identity is not as highly regarded as fingerprint evidence; (2) comparison of handwriting specimens must be used with great caution as witnesses looking for similarities are unlikely not to find any, potentially involving unconscious circular reasoning; (3) the Court itself examined the questioned documents and noted dissimilarities that could not be overlooked, though it was uncertain whether these were genuine or the result of deliberate disguise. The Court also observed that the quality of photographs on metal Identity Cards are "far from high quality, award-winning portraits" and that it must be a possibility that conspirators could find someone who could pass as Taruvinga based on a poor quality photograph.

This case is significant in Zimbabwean and Southern African labour law for establishing important principles regarding: (1) the burden of proof on employers in disciplinary proceedings, particularly where dismissal is sought; (2) the need for employers to produce all relevant evidence, especially when ordered by a court, before negligence can be established; (3) the evidential limitations of handwriting expert opinion evidence and the requirement for corroboration; (4) the proper application of banking procedures and the importance of factual accuracy in misconduct allegations; and (5) judicial deference to Labour Tribunal findings of fact where they are not demonstrably irrational. The case demonstrates the high standard employers must meet to justify dismissal and the courts' willingness to protect employees from dismissal based on insufficient or unreliable evidence.
